The present invention relates to air moistening means for furnace flues'andinore par- I ticularly to the type provided with air moist eningmeans, an ohjectjthereof being to pro-' vide a moistening means which Wlll be effectivein' operation. andnot liableto get out of order. 7'

I To thisand-other ends,'th'e invention c0115 sists of certain parts and combinations of 1 parts all .ofjwhich willbe hereinafter de 7 p around one end, and then over-the top, of", ,each evaporating receptacle. The supply receptacle 12 has; a; discharge in the hot .70

in the appended claims -In;the drawings':.

scribed, the novel" features being pointed out Fig. 1 isa face viewof a'verticaliflue 5 which the present nvention is embodied;

shown .in' vertical section;

Fig. 3 is a top view of the flue; 'Fig. 4; isa front view of the grille which Fig; 2 isa side view of the flue withparts covers the open upper end of the flue; and

Figs. "5 and'6 are detail viewsof the cooperating valve members which contr'l the opening upper end ofthe flue.

Referring more "particularly to the drawings, v1 indicates the 'fl'ue'whiclnin this instance, is rectangular incross-sectionand is formed of a number of superimposed sections. The lower section has an intalre'opening 2 on one face thereof, while, the upper 0 section is provided with an outlet opening 3.

This opening is preferably controlled by a valve comprising a fixed plate A arranged in front of the opening and a sliding plate I 6, both these plates being preferably mounted in a casing 7 supported by brackets- 5 and having its front covered by a grille: or plate 8. The plates 4 and 6 may be provided with transversely extending slots9 which, when registering,"provide for the outlet of the heated aiig and when out of regis- Ite'r close the upper end of the flue.

10 rigidly secured thereto and extending through a slot 11 in thefixe'd or stationary plate4.

Within the flue, preferably in the upper section thereof, a supply receptacle-12 is mounted, this'receptacle having a filling The, sliding plate 6 preferably has a finger piece mutant fil edlAugust 2o ,'192 o,fsen a1 ms. 404,825; n n ea'octote so; 1925 take into the flue. 1 Between intake and the outlet the flue may be provided with any desired. numberiof open or evaporating re- I ceptacles 14, these receptacles preferably being arranged in staggered relation by projecting fromopposite side walls of theflue and being spaced from'one of the side walls tom thereof which connects, by a tube v 16,

lowit. Each evaporating receptaclefhas an overflow connection with the receptacle next below it, this overflow connection being pref-- erably formed by atube 17 which projects lt ab'outthe opening 18 in said bottom. A tubing 19 also projects about the'opening endof the tube 17 in'the evaporating reupwardly from the bottom'of the receptacle" v18 downwardly from the bottomv of each t evaporatingreceptacle and abontthe upper o ceptacle next-below it, the tube-19 being of slightly greater diameterthan the tube i i 17 so that a space is proyided about the tube 17 through whichthe overflow ,may

take place. The tube 19 of thelowermost evaporating receptacle-14depends into the receptacle 13.

With .the end tin View of preventing the overflow of the receptacle 13, the latter may be provided with a float '20, and this float has 'a' stem. 2l'projecting upwardly therefrom to the supplyreceptacle 12, a valve 22 being arranged upon said stem" and being adapted, when the receptacle 13.is filled, to close the discharge opening 15 of the supply receptacle 12.

I It is apparent that this construction'causes the series of evaporatingreceptacles 13 and '14 to .be-maintained' infilled condition as long as there is any water'in the receptacle ioo 12, because the water ,Will flow from the receptacle 12 except whenthe'receptacle 13 is filled, and, when this receptacle 13 is filled,

the other receptacles, with the exception of the supply receptacle, must necessarily be filled. It will be noted thatthe flue may be made of any desirable length by introducing between the inlet section and the outlet sec tion any desired number of intermediate sections with evaporating receptacles therein, it being necessary, only to lengthen the.

rod 21 to correspond to the length of the flue.

lVhat I claim as my invention and desire to secure by Letters Patent is:

1. In combination with a vertically arranged flue, having an inlet at its bottom and an outlet at its top, a supply receptacle arranged adjacent the outlet provided with a discharge and a valve controlling said discharge, an open ended receptacle arranged adjacent said inlet, a plurality of open receptacles, one arranged above the other between the inlet and the outlet, the upper one of said plurality of open receptacles receiving liquid from the supply receptacle, overflow connections between the open receptacles, and means in the lower receptacle having connection with the valve of the supply receptacle extending through the overflow connections for controlling the flow of liquid from the supply receptacle to the open receptacle next beneath it.

2. In combination with a vertically arranged flue having an inlet at its bottom and an outlet at its top; a supply receptacle arranged adjacent said outlet, an open receptacle arranged adjacent said inlet, a plu rality of open receptacles arranged in staggered relation one above another between the inlet and the outlet, overflow connections between said open receptacles, a float in the lowermost open receptacle, and a valve for controlling the flow of water from the supply receptacle to the uppermost open receptacle.

3. In combination with a vertically arranged flue having an inlet at its bottom and an outlet at its top; a liquid supply receptacle arranged adjacent the outlet, a plurality of open receptacles arranged below said supply receptacle one above the other, overflow connections between the open receptacles, a valve for controlling the flow from the supply receptacle to the uppermost open receptacle, a valve stem extending through the overflow connections, and a float connected to said valve stem and arranged in the lowermost open receptacle.
